6 TVs Trends leading to increased TV energy use: High Definition Larger Screen Sizes On more hours per day ( cable TV, movies, video games, etc.) 3D may also result in higher power use Decreasing retail price for flat panel TVs makes them more affordable, especially for developing economies New installations such as hotel lobby, fitness center, airports, restaurants, etc on continuously most of the day. May represent 2% or more of a nation s overall electricity use. 6

7 Worldwide TV Energy Consumption Compared to Some Major Countries 7

8 TV Model Energy Use In 2008, some big screen TVs consumed >500 kwh/yr, or more than a new US refrigerator Due to labeling programs, incentives and mandatory standards (MEPS), dramatic reductions in TV energy use seen (30 to 75%) Today s best plasmas use 3X less power than earlier models LED backlights helping reduce LCD power use 8

10 TV Levels in U.S., EU, and India *Note: India testing is done with a static test clip as opposed to the dynamic test clip used for all others. Wattage is also estimated based on kwh/yr requirements, assuming 6 hours on per day as shown in 10

11 Note - On Mode Power Represents Most of a TVs Annual Energy Use 11

12 Analog to Digital Switch is a Big Deal Analog to digital switch will drive market towards new TV, STBs, and Digital-to-Analog convertor boxes Strive for new DTAs to use <6W and to automatically power down to <1W after extended period of user inactivity. Source for Figure 101: International Energy Agency. Gadgets and Gigawatts (2009) 12

13 India Goes Digital in 2014: Opportunity to Encourage Most Efficient TVs & STBs as a result, there will be strong demand for set top boxes the government is also planning to incentivize the STB and head-end equipment sectors incentive for consumers to upgrade from CRT to LCD TVs 13

15 Current Computer and Monitor Data Today s Computers Today s Monitors Includes Category A&B ENERGY STAR PCs as of March 1, Includes ENERGY STAR and CNET (http://reviews.cnet.com/green-tech/monitor-comparisonchart/?tag=contentmain;contentaux) data as of March 1,

16 STBs 1. Types of set top boxes: Digital to analog (DTA) receive free broadcasts for older CRTs Basic box cable, satellite or IPTV Digital Video Recorder (DVR) able to record and playback content 2. Most boxes have little to no power management use near full power 24/7 3. Recent US study showed $2 billion/yr spent to power boxes that were not being actively used and six power plants worth of electricity (500MW) 16

20 70% of energy use is when units are not displaying or recording video Poor power management - STBs should sleep when we sleep. Equivalent of 6 large power plants are needed to power our STBs when they are NOT recording or displaying content. [3] This translates to: 19 billion kwh/year $2 billion / year in user electric bills [1] 11 million metric tons of CO 2 / year [2]

21 Video Game Consoles Growing in popularity. W-wide Installed base: Sony PS3 Microsoft Xbox 360 Nintendo Wii 48 million 52 million 85 million New models are like mid range computers. Now able to connect to internet, stream and playback movies, etc. 21

25 Video Game Console Observations 1. Manufs ship device with auto power down disabled if you forget to turn it off, continues to operate at near full power levels. For some models translates into approx 800 kwh/yr. 2. Models not optimized for energy efficiency movie play power can be 4-8 times higher than for stand alone Bluray DVD player. 3. Industry has recently been working hard to reduce on mode power use. 4. Need to make sure next generation of consoles are energy efficient and include power scaling chips. 25

26 Advice and Priorities Policy combination of product labels, mandatory standards, (and incentives, if applicable), is most effective approach for encouraging market transformation Great example is TVs Test procedures matter (in particular set up conditions prior to testing) Policy can still be effective even if market is moving fast Need to pay attention to the cloud Smart electronics and home area networks will be a growing market over next decade 26
